In my outfit (Northern Europe), we normally deice numerous times a day during the dark season. We have a "pretakeoff check" to be performed within 2 min of starting takeoff roll. Said check may be performed in 3 ways: 1. Mental review 2. Check of representative surface, and 3. Check of wings.
Our representative surface is determined in our FCOM (A320) as the left wing root area (so 2 and 3 are basically the same)

Now, for all practical purposes, I will only make a mental review (HOT still valid / no adverse change in met conditions since deice / not behind another aircraft too close as to get jet blast blow my fluids off etc etc). Should I for some reason be so unsure wrt my protection as to consider moving out in the cabin and politely ask a passenger to move over so I could check the wing (bad psychology...), then I would simply taxi in for another spraying session.

Rgds,
